modifications of apparatus Yfor removingcarbon deposit frornthel valves of internal .combustion engines as set forth in the sp'eciicationofmy cof 'pending United States Patent application lSerialv Number 302,615, ledlNovernber 2, `l939,'.which matured as Patent1N0..,2272,636, Feb;'10, 1942.

In thev aforesaid, means are provided for vrotating the valve on itsaxisiand-separatemeans for swivelling a nozzlethe discharge from `whichis directed onto the face and neckvof` the valve. According to the present invention, a common operating means isprovided whereby thefvalve is rotated on its axissimultaneouslywithzthe swivelling actionner" 'the nozzle which deals with the face` and neck.

Thus, and in the general method of carrying the invention into effect, the means which rotates the valve/with its stem on the axis of this latter (when the valve is mounted in position) through intergearing or otherwise brings into action the means for moving the nozzle concerned with cleaning the face and neck of the valve.

This means may include toothed gearing or belt gearing or otherwise which preferably has a reduction ratio. Asa consequence thereof the valve to be cleaned'may be rotated on its axis a desired number of times during the traverse of the spraying and cleaning action of the jet from the nozzle cooperating with the neck and the face of the valve, whilst the off-centre nozzle remains in action for its jet to clean the crown of the valve.

In order that the invention may be better understood, it will now be described with reference to the accompanying drawings, which are given by way of example only and in which:

Fig. l shows an exteriorfelevation of one form of apparatus constructed according to the invention.

Fig. 2 shows a sectional plan through the axis of rotation of the valve, and Y Fig. 3 shows a side elevation ofA Fig. 1.

In the `particular method of carrying the invention into effect shown in the drawings, a generally rectangular main casing 4 is provided, open at the top and closed at the bottom except possibly in a position for the escape of the cleaning particles (shot or the like). This casing is vprovided with a cover v( (preferably as shown Aof somewhat truncated pyramidal form)'which may or may not include a window such as '|,With or without an illuminating lamp such as 8.

Further, this cover is hinged at one edge at 9 and has a clip I on another edge to facilitate :Application April rv7, 1941,:sria1 Nolan-344 'Y f In Great ritain April 29, 19.40 -f 4 v j. w l v (CI. 51.-15) This invention relatesl to improvements in or the: Hopen-inlgfand: .the placing inl; positivonfofV the valve withits stem l2ftovbecleanedif Within' ,themain chamber formed by the'casing 4 there are disposed -thetwo-main nozzles I3 and |.4 together.with`their ,connections; theone I3 being xedand disposeditl come slightlyfoif the axis of` thevalveand'stem tobe' cleaned' (when mounted in position) ,fits jet71 being directed" to `the crown thereof, thegother` 4 being 'somounted that itcan have a swivelling action and disposed.

so that, its jet is directed .to the-neck-andface of the valve (whenmounted in position).;V 1 g z Exteriorofthe main casing vand-attachedto one sidepthereof there'is :provided fanj'additional vhousing-I5 which includes a bearingror journal I6 to receive a sleeve constituting the exterior of achuck.` At one endk this sleeve the interior of the main casing 4,'

These Washers 2| or thisv f sleeve are abutted at the yend remote from the packing washers 20 bythe open end 22 of a hollow cylinder 23 having the other end 24 closed and being slidably mounted in the end 25 of the -exterior sleeve I of the chuck.

This end 25 of the chuck sleeve is closed and has an exterior ange 26 which abuts a partition f21`extending across-the exterior housing I5. 'I'his closed end 25 is formed rwith an apertured boss 28 to which is secured ra hand-wheel 29 for rotating the sleeve 'l in the bearing or journal I6 and the central kspindle3l) is bored forl the passage of a clamping rod 3| screwthreaded towards the exterior and terminating in a clampinghandle-y 3|' on the interior abutsi A the closed` end 24' of the sliding cylinder23 andy 32. This screwed rod consequently by turning the clamping handle 32 this sliding cylindery compresses the rubber Washers 2|. This compression action causes the said washers to grip the stem I2 of the valve I when the same has been inserted in position. Similarly, by releasing the clamping means, the'said stem readily can be remove f The partition 21 in the housing I5 also has a bearing or boss 33 for a gear wheel or pulley 34 of comparatively large diameter which meshes projects into# Where its ex-r4 terior diameter isreduced at IB'and has a screw f This latter receives a stems|2 of the valves to vbe y the chuck is turned to rotate the valve and stem Il-I2 the said nozzle' I4 is caused to swivel.

If desired, the exterior of the chuck sleeve I1,

which rotates in its bearing or journal I6, may,

as shown, be channelled or grooved at 40 to receive a suitable lubricant through `a greasingf.

nipple or the like 4I. o

Although a particular mechanism has been described forefie'cting the rotational movement of the valve andthelswivelling action of the nozzle, it will be' understood that the invention. is not limited thereto/,as this combined action may be carried out in a great'variety of manners.A VWhat I claimy and desire. to secure by Letters Patent of the UnitedStates of America is:

1; In an apparatusfor removing carbonrdeposit from valves, thecombination of a housing, a noz- .zlefmovably lo'ca'tedvin4 the housing, a secondary housing adjacentl said iirst named housing, a supportforthe valve to be cleaned in said secondary housing, said support being arranged to projectla portion ofthe valve intovthe rstnamed housing, clamping meansfo'r said valve in said 43'.
